The following four captured German Abwehr documents illustrate how Operation Mincemeat was swallowed hook, line and sinker. Each of the original documents beared the initials of Admiral Doenitz.
Digging around in the National Archives yesterday I came across this correspondence regarding Operation Mincemeat.
The story of Mincemeat was originally told in 1950 by Sir Duff Cooper in his book 'Operation Heartbreak'. The book claimed to be a work of fiction but was very close to the real story. Obviously Commander Montague was not best pleased when Duff Cooper published this book, as he wanted to tell the story himself.
This correspondence, between members of the Joint Intelligence Committee, discuss why they did not want the real story told. Nevertheless, in the end Montague was able to publish his truthful, abeit incomplete, account of Operation Mincemeat which led to the famous film "The Man Who Never Was".
